In CoD, most of the maps are 100yds. And you can't compare a rifle to a pistol damage wise. Even a beefy .45ACP won't do as much damage as a standard .308. That said, this was about difficulty of shooting a pistol at 100yd+ marks and how that is relative to shooting a rifle 800yd+.
This wasn't about the difficulty of shooting at what distance with accuracy.
I made the point of saying 'as pointless as using a pistol for sniping'.
I never specified.
It was a general point.
